V-grinds work just fine, as has been stated. I prefer them, and still free-hand sharpen some of my knives on stones.
Busse edges all come with at least some convex shape to them. The first time you sharpen it to a tru v-shape, you'll have to flatten that shape out and it takes longer that time to re-profile the edge. I use course stones on the EdgePro for that to save time, but it can be done by hand, too. I've also got some metal diamond-coated rods for a crock stick block, and they work pretty fast also, although I try to stay away from using crock stick sharpeners if I can, except for certain knives.
